Freaking out

Hi. I’m an idiot and i had unprotected sex a week ago with a guy i hardly know.

I am not on birth control.

He did NOT finish inside of me but i am just super paranoid that I’m pregnant.

I had spotting for two days on Monday and Tuesday this week. I was afraid it was implantation bleeding. I never spot.

But i read that usually happens 6 days after sex or so??

I haven’t had any other symptoms... granted it’s been a week...

I’ve convinced myself my boobs hurt now. But I’m not sure they do or I’m freaking myself out.

I have two weeks until my period.

How high are the chances I’m pregnant
